My project consists of: 5 4051 multiplexer chips (31 pots connected to 4 chips, all connected to "master" 4051) 6 4021 registers (46 buttons) 4 74HC595 registers (27 LEDs) 1 LM324D amp Now I was thinking of separating the power lines like this +5V from arduino to 4021+74HC595+LM324D, GND from …

Need advice on powering lots of chips
